The Game Boy is an 8-bit handheld game console developed and
manufactured by Nintendo. It was first released in Japan on April 21,
1989, in North America later the same year, and in Europe in late 1990.
It was designed by the same team that developed the Game & Watch series
of handheld electronic games and several Nintendo Entertainment System
games: Satoru Okada, Gunpei Yokoi, and Nintendo Research & Development.
It is Nintendo's second handheld game console and combines features from
both the Game & Watch handheld and NES home system. The console features
a dot-matrix screen with adjustable contrast dial, five game control
buttons (a directional pad, two game buttons, and "START" and "SELECT"),
a single speaker with adjustable volume dial and, like its rivals, uses
cartridges as physical media for games.
The color scheme is made from two tones of grey with accents of black,
blue, and dark magenta. All the corners of the portrait-oriented
rectangular unit are softly rounded, except for the bottom right, which
is curved. At launch, it was sold either as a standalone unit, or
bundled with one of several games, among them Super Mario Land and
Tetris. Several accessories were also developed, including a carrying
pouch, a camera, and a printer.
